Specification of Letters Patent.

Patented Feb. 1.9, 1907.

Application filed May 31, 1906. Serial No. 319,418.

To all whom, it may concern,.-

Be it known that I, JoHN Summer, of

' Rochester, in the county-of Monroe-and'State of New York, haveinvented -a certain new .and useful Sight-Feedl for Lubricators, of

which the following is a ,specific-ation.

My invention has for its object the production of a sight-feed forlubricators which is particularly simple in construction and economicalin manufacture; and to this end it .consists in the novel combinationsand constructions herein-after set forth and claimed.

In describing this invention reference is had to the accompanyingdrawings, which like characters designate corresponding parts in all theviews.

Figures l and 2 are respectively front and side elevations of oneconstruction of my sight-feed and contiguous parts. F ig. 3 is asectional view, partly in elevation, on line A A, Fig. 1.

My'sight-feed for lubricators comprises opposing 'sect-ions 1 and 2,spaced apart, a

transparent or glass shell 3, interposed between said sec-tions,clamping means for forcing one section toward the other and for holdingthe sections from movement relatively to each other, and means forprevent-l ing the transparent shell from receiving the strain of t-heclamp-ing means. p

As i-llustrated, t-he sections l and 2 are respectiVely, a base and acap, and their oppos- `ing surfaces are Aformed with sockets 4 andannular bearing-faces 5 within the sockets.

The base 1 is formed with inlet and outlet openings 6 and 7, theinlet-opening'extending through the bottom of the socket 4 eccentric tothe center thereof and communi- :ea-ting with a'source of supply, as aforcefeed lubricator, (not illustrated,) and the v outlet-openingextending through the center of the bottom of the socket 4 and communi-4eating with a part to be supplied with 4lubri- (Not shown.) Said'outlet-opening 7 is also provided with a suitable check-valve 8 forpreventing the escape of steam in case the transparent shell 4is broken.A conduitQ, communicating with the inlet-opening V6, rises from thebase, and its upper end terminates below the cap 2, is downturned, andis provided with an exit arranged over the outlet-o ening 7.

' The transparent shell 3 is of less diameter than the sockets 4, andits ends extend into the sockets 4 beyond the annular bearingfaces 5.Said shell 3 is of less length than thedistance between 'the end wallsof the sockets 4.

The clamping means may be of any desirable form, size, and construction,and is here shown as consisting of members or screws 10, caocting withoutwardly-projecting lugs 11, formed on the sections 1 and 2, saidscrews being movable in the lugs 11 relatively to the sections 1 and 2.

The means for preventing the transparent shell from receiving the strainof the clamping means comprises a metallic sleeve and packings 12. Thesleeve is separable from and interposed between the sections v1 and 2,is independent of the clamping means 10, and encircles the shell 3, andits ends extend into the sockets 4, cooperate, respectively, with theannular bearing-faces 5, and are formed with beveled end faces. Saidsleeve is formed with windows or openings .13, spaced apart, whichdivide the'sleeve into collars 14, located at the ends thereof, andlengthwise members 15, spaced apart and connecting the collars. The,packings 12 are interposed between the beveled end faces of the sleeveand the annular bearing-faces 5, and are firmly forced against the innerupright faces of the sockets 4 and the periphery of the shell 3.

A sight-feed for lubricators constructed as described may be cheaply andeconomically manufactured and is particularly durable in use, since nofitting of the glass shell is necessary in order to make a tight point.

What I claim is- 1. A sightefeed for lubricators comprising opposingsections spaced apart, a transparent shell interposed between saidsections, clamping means for forcing one section toward the other andfor holding the sections from movement relatively to each other, andmeans interposed between said sections for preventing the transparentshell from receiving the strain of the clamping means., thesecond-mentioned means being separable from the opposing sections andindependent 'of the clamping means, substantially as and for the purposedescribed.

2. A sight-feed for lubricators com rising opposing sections spacedapart and 'ormed Withnannular bearing-faces, a*transparent shellinterposed between said sections, and l extending beyond saidbearing-faces, clampl l ing means for forcing one section toward thewithin the sockets, a transparent shell interthe annular bearing-facesand the beveled other and for holding the sections from movementyrelatively to each other, and a sleeve separable from the opposingsections and independent of the clamping means', said sleeve encirclingthe transparent shell and cooperating with the annular faces, and beingformed with openings spaced apart, substantially as and for the purposeset forth.

3.
